The Practicality of Using a Three-Dimensional Fast Fourier Transform in Auto-Indexing Protein Single-Crystal Oscillation Images

The feasibility of using a three-dimensional fast Fourier transform as the basis for determining the crystal cell and orientation from a single monochromatic oscillation image of a protein crystal has been investigated. The results of tests, carried out for both simulated and real data-sets, are presented and confirm that a practical method of auto-indexing can be developed.
